Location

These vertical walls of rhyolite tuff (pronounced toof), which look like Swiss-cheese cliffs made of unpolished marble, are the result of a powerful prehistoric volcanic eruption that blasted rocks across the landscape. Learn how the site got its name by hiking the 0.5-mile Rings Loop Trail where metal rings lead down through a narrow slot-canyon once used by Native Americans to escape 19th-century ranchers.
